French adventurer and researcher Stephane Rousson prepares Aerosail, an innovative, efficient, and silent maritime vehicle, which uses only the wind as means of propulsion. Its unique principle of flight allows the user to pilot like a sailboat an airship linked by a cable to a stabilized keel, called the Seaglider. The cable acts as the mast and the airship as the sail. Rousson is planning his crossing for the end of October 2014. Text and photos courtesy of AFP/Getty.
